Objective—To compare results of hematologic testing in nondiabetic and diabetic cats to identify possible indicators of alterations in long-term glucose control.
Animals—117 client-owned cats (76 nondiabetic cats [25 with normal body condition, 27 overweight, and 24 obese] and 41 naïve [n = 21] and treated  diabetic cats).
Procedures—Signalment and medical history, including data on feeding practices, were collected. A body condition score was assigned, and feline body mass index was calculated. Complete blood counts and serum biochemical analyses, including determination of fructosamine, thyroxine, insulin, and proinsulin concentrations, were performed. Urine samples were obtained and analyzed.
Results—Glucose and fructosamine concentrations were significantly higher in the naïve and treated diabetic cats than in the nondiabetic cats. Insulin and proinsulin concentrations were highest in the obese cats but had great individual variation. Few other variables were significantly different among cat groups. Most cats, even when obese or diabetic, had unlimited access to food.
Conclusions and Clinical Relevance—Results suggested that cats at risk of developing diabetes (ie, overweight and obese cats) could not be distinguished from cats with a normal body condition on the basis of results of isolated hematologic testing. A longitudinal study is indicated to follow nondiabetic cats over a period of several years to identify those that eventually develop diabetes. Findings also suggested that dietary education of cat owners might be inadequate.
Objective—To compare owner-assessed ease of administration and overall acceptability of 3 chemically inactive formulations administered PO to cats.
Animals—90 healthy client-owned cats.
Procedures—Cats were randomly assigned to receive 1 of 3 formulations PO once daily for 14 days: medium chain triglyceride (MCT) oil, dissolving thin film strips (proprietary ingredients), or gelatin capsules filled with microcrystalline cellulose. Owners administered the formulations and rated ease of administration daily on a 10-cm visual analogue scale (VAS). At the end of the study, owners rated overall acceptability of formulations from their own perspective and their overall perception of acceptability to their cat.
Results—Mean VAS scores for daily ease of administration of MCT oil and film strips were significantly higher than scores for gelatin capsules at all time points, except on days 2, 4, and 7. There was no difference between MCT oil and film strip formulation scores. Mean VAS scores were 8.8 (MCT oil), 8.9 (film strips), and 7.4 (gelatin capsules) for overall acceptability to owners and 8.0 (MCT oil), 8.3 (film strips), and 6.7 (gelatin capsules) for overall owner-perceived acceptability to cats.
Conclusions and Clinical Relevance—Daily ease of administration on 11 of 14 days and overall owner-perceived acceptability to cats were scored significantly higher for film strips and MCT oil, compared with scores for gelatin capsules. Overall acceptability to owners followed a similar pattern; however, the differences were not significant. Dissolving thin film strip or MCT oil vehicles may allow for easier PO administration of medication to cats than does administration of gelatin capsules.
